5 of Missouri, have invented certain new and useful Im rovements in Electrical Curling- Irons; an I do declare the followingto be a full, clear, and exact descri tion of the invention, such as will enable ot ers skilled in the 10 art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to the-letters and figures of reference marked thereon, which form a art of this specification.

.y-invention relates to curlin irons, and more particularly to adevice 0 that class which receives its heat from a unit contained in one of the bars of the iron, and is connect ed with a suitable source of electrical suppl It is the object of m invention to provid e an iron of that class aving a heating unit of limited resistance which may be laced in series with a lamp or other article a apted to receive electrical energy, in a manner to preof the iron. In accomplishingthis object I have provided the improved details of structure which will presently be fully described and (pointed out in" the claims, reference being ha to the accomforming part of this s ecilike reference numer s re fer to like parts throughout the several views, and in wh1ch Figure I is a generalview of acurling iron constructed accordingto my invention,

own that I,-TREVOR M. OAVEN, a

of which projects into, the

I parts 1 indicates a cylinder which forms part of one Patented fla 19, 1903.

which is wra ped on a suitable core 4, and provided wit a acking 5, between the coil and cylinder-shell.

The ends 6 and 7 of the coil are extended backwardly through a channel in handle 2 or through the integral handle ortion 2, to a s'ocket'8, where the end 7 is so dered or otherwise securedto the bottom of alwell 9, of

brass or other conductive material, which is threaded at its outer end into afiber or likecollar 9' carried in a brass or like tube 10, which tube is of such diameter as to fit loosely into socket 8.

Seated in well 9 is a coil spring 11, and

resting on spring 11, with its freeen'd projecting out of well 9 is a plunger 12, both the spring 11 and plunger 12 being of asuitable tudinallyperforated plug 14. Extending through neck 13 is a wire 15, the inner end erforation in lug 14 an is there anchored y a screw 16 avinga head 17 adapted to contact with the outer end of plunger 12. Threaded onto the outer end of tube- 10 is a ca 18 having a perforation in its head throng which neck 13 projects, and in which 'said neck may free y revolve while the inner surface of said head' covers the offset portion .of the neckto prevent its escape from the socket; cap 18 eing of a diameter to fit snu ly into socket 8, and is adapted when so tted to bind the second coil wire 6 between its outer surface and the inner surface of the socket.

Fitting snugly over the outer end of neck 13 is an insulated button '19 having a longitudinal perforation therein, through which the wire 15 extends and into which a second wire 20 projects, the latter being anchored 'between. the louter surface of neck 13 and the inner surface of saidbutton when the latter is forced over the former;

Wins 15 and 20 may be wrapped to ether to form the cord 21 and lead to a soc et 22 carried by abracket 23. Socket 22 has a.

suitable mechamsm forfcontact with the feed wires in the bracket andone of the wires 15--20 contacts with suchme'chanism e;

and the-other-with the parts which conduct 45 contact with the feed wire 20.

rent from thefeed Wires must pass through 1 the coil in 'the curling iron cylinder and through the lamp. The coil in the curling iron cylinder is composed of wire having a resistance only sufiicient to heat the 'cu'rhn iron to a desired temperature so .that shoul the iron be attached to 'a socket having feed wires of a'higher. potential than is necessary for the plroper operation of the iron the excess W1 pass through the curling iron coil into the lamp. In this manner the curling iron may be used with a current of any strength, without danger of overheating the iron or burnin out the-coil.

25 is a plug coated in the end of cylinder 3 and 26 1s a clip ofany ordinary construc-.

tion, having ears 27 through which the pivot m. 28 ro'ects; said in also rojectin iihrough cyliinder 1 betiveen the coil end: and serving as an anchor to prevent the displacement of the coil.

29' is a' sp'rin adaptedto' normall ,-retain 3lip 26in yiel 'ng -engagement wit cyliner 1.. In assembling the parts the wire 6-7, is projected through the cylinder 1, coiled on the core 4 and returnedto the cylinder and I acked with the asbestos or suitable insuatin body 5. The end plug 25 is then sefcure inposition and the wire end-7 secured to the'well 9. The wire 15"is then secured in its plug by means of screw. 16 and the button pushed over neck 13, anchorin wire 20. The parts carried in socket 8 are orced into place ,anchoring the end 6 of the cu'rling iron coil, and the other parts arranged in the customary manner.

When the current is turned on, ;a circuit isr nade through the screw 16, the head of tween the movab to a coupling which contacts with plunger 12,-and the spring 11 which connects'the plunger and bottom of well 9 to which the end 7;of the curling iron coil-is secured. On the return, the coil end 6 contacts with cylinder 10 which carries neck 13,1 the latter having a the curling iron is turned in'handhng,

neck 13 revolves freely in the 0 linder and anchor cap without turning cor 21 sov that kinkin or binding of the cord=21 is obviaterialthough a perfect contact bep e and stationary parts of the swivel is always had through the yielding plun er 12.-

As be ore stated, my preferred form of ;heating unit, is the. coil shown in Fig. I and "described in detail in the presentspecification,- although,- a number of modifiedforms of heating unit ma be utilized according to the general pri'n'cip e of my imlplroved device. In Fig. II I show the coil w 'ch is secured block A, with the wires 67 connecting b ock A with the swivel.

.Z In ri 1v 1 Show a bulb D containing suitablefilamentsthe bulb being carried inhandle semen the socket E, the F G being connected with the socket and with the swivel (not shownineither of. views IV and V).'

' In Fig. VI show a heating rod H, carried between block I and a-socket J, witha wire K running through the-block and connected .with the outer end ofthe rod and a wire L connecting the inner end of rod H with the swivel, so that when current is applied 'a circuit is .made through the parts.

. While I have specifically described the\ swivel which I use in connection with my iron, I make'no'claim-thereto in this a plication, as it is shown and claimed in t e application filed by me the 18th day of 1907, which is serially numbered 374,362.
